LUMBER-JACK.

Specification of Letters Patent. Pate ted N 14., 1911 Application filed November 10, 1910. Serial No. 591,,5s:.

To all whom it may concern:

Be it known that I, LUTHER S. PERDUE, citizen of the United States, residing at Waycross, in the county of Ware and State of Georgia, have invented certain new and useful Improvements in Lumber-Jacks, of which the following is a specification.

My invention relates to lumber handling devices and refers more especially to that type of apparatus commonly termed a lumber jack which is designed to facilitate the local transportation and piling of boards and timbers of the heavier sort, and particularly to aid in loading and unloading the pieces from trucks or other lumber conveyers.

The chief objects of the improvements which constitute the subject matter of this application for patent are :to provide simple and effective means to be used in connection with a lumber truck or buggy for expediting the loading and unloading of the lumber, the device being also useful for piling, or moving lumber wherever boards and timbers of the larger sizes are to be handled, and to furnish an appliance for the pur ose stated that will be strong and durab e, and require few. parts in its construction.

An especial feature of my improved device for handling lumber of all kinds and dimensions is that the standards already in use upon ordinary lumber buggies may be utilized as supports for the pivot rod or fulcrum bar by slight modifications, thus conducing to economy in the manufacture.

I accom lish the desired results above enumerated and others of importance by employing the device illustrated in the accompanying drawing which forms a part of this application, the details of construction being shown in the following views.

Fi re 1 is a perspective view of a lumber figgy embodying my im rovements; Figs. 2 and 3 are side and en elevations,

respectively, of the yoke and standards, and

buggy. The bed or frame is of the usual form, comprising side beams 7 connected at the ends by cross pieces 8. It is usual to suppl such lumber vehicles with standards or sta 1:8 to prevent the lumber loaded thereon from coming in cc ntact with the wheels and also serve as sup ports upon which the lumber is rested when tipped from the load. Two such stakes or sta ndards 9 are shown in the drawing arrangel, opposite each other on the bed and modifie :lffrom the usual form to cooperate with the fulcrum or slip rod which will be hereaftl r described. For the purpose of making a i rm and solid foundation for the standard; the latter are made of a single piece, the niddle portion of the bar entering into tl eir formation being shown at 11 extending transversely to the bed of the truck. Tl is bar or yoke is secured to a cross bean 12 of the frame by bolts 13, and the ends of the yoke are bent vertically upwardly tc form the said stakes or standards 9. The upper extremities of the standards are bent outwardly in a horizontal direction as she vn at 14: and strength ened by braces 15 f0] med by bending the ends of the bar formir g the standard in the manner shown, the cm is of the braces being welded to the upright portion of the standard, as indicated at 16 thus forming an exceedingly strong bra ket. The horizontal portion 14 of the stand LI'dS and the diagonal braces 15 are pierced ly holes 17, 18, which form sockets in which is inserted one end of 'a round slip rod or l ver-10. This rod is furnished with collars 50, forming stops, one of which will engage the arm 14 of the standard when the lev :r or rod is placed in the socket holes, and t nus hold it at the desired height. The sail stops or collars 20 are located at difierert distances from the adjacent end of the r0 1 or lever so that the height which the uppi r end projects above the bracket may be va ried by reversing the lever. Each end of th: lever or rod is beveled to form a point 21. which will'enter the piece of lumber when placed thereon and prevent it from slipping off while being tipped from the buggy While I have shown two collars on the tip rod 19 it will be evident that a single collar will answer the s one purpose and may be considered an equiv: lent therefor.

The manner of usin;, my improved lumber jack will be readily understood. The pivot or fulcrum bar having been slipped into its socket upon 01 e side of the buggy, the side selected depen ling upon the direction in which the luml er 1s to be disposed, the pieces are then re .sed at one end and rested about the middle upon the pointed end of the slip rod 19, and when properly engaged the other end of the lumber can be easily raised by bearing down upon the shorter end and the piece is then swung around upon the point 21 as a fulcrum or pivot until in the required position, when the plank or beam is raised from off the slip rod and deposited in the pile which is being formed. It will be seen that this procedure is similar to that usually followed in loading and unloading lumber on and off a common wagon, the jack facilitating the operation, rendering it easier and more expeditious than when no similar aid is employed, and enabling one man to pile timber pieces which would otherwise require two to handle.

Having thus described my invention, what I claim as new, is 1. In a lumber buggy, a standard consisting of a flat metal bar rigidly secured to the frame of the buggy and extending upwardly at right angles to said frame and having a horizontal portion and an inclined portion all integrally formed, and the end of the inclined port-ion rigidly connected with the upright portion, and said horizontal and inclined portions provided with a-linedopenings, in combination with a rod detachably and reversibly mounted in said openings.

2. A lumber jack comprising a one-piece standard having a vertical portion, a horizontal portion extending outwardly from the vertical portion and an inwardly in clined portion extending from the vertical portion to the horizontal portion, and said horizontal and inclined portions having ver tical alined openings therethrough.

3. In a device for the purpose stated, the combination with a truck, including a body, of a bar extending transversely to said body and having its end portions bent upward to form standards, a pair of brackets formed on each standard, and having holes in alinemerit, a reversible fulcrum bar adapted to removably engage said holes and provided with a pair of etc s thereon arranged at varying distances rom the corresponding end of the bar.

4:. A lumber jack, comprising a pair of standards integrally connected by a horizontal bar, the upper ends of the standards being bent outwardly and then downwardly to form brackets, the end of the bent portion being welded to the body of the standard, said brackets having holes therein forming sockets, and a pivot bar adapted to removably engage the sockets. 5. The combination with a lumber buggy, of a pair of standards integrally connected,

the ends of the standards being bent out i wardly and then downwardly, the extremities of the bent portions being welded to their respective standards, the said bent portions having holes arranged in a-linement 7 to form sockets. y

In testimony whereof I affix my signature in the presence of two witnesses.
